#askthefediverse which #foss productivity apps do you use? And how are they integrated?

Use case: starting a new job, taking a uni course, writing a masters thesis, plus personal goals to achieve. Walking around with a massive to do list in my head.

I'm trying out apps to keep track, but they're not integrated. Think mail in one app, calendar in another, Nextcloud + deck, tasks in a notes app. Since it's not integrated, I'm often doing double work or lose track. How do other people do this? 🤔
